FRA application
Background
The Frequency Response Analyzer (FRA) is a
feature application for digital storage oscilloscope
with an integrated arbitrary waveform generator.
It can plot gain and phase responses at the output
of a device-under-test (DUT) when its input is
excited by a frequency-swept sinusoidal signal.
Bode plots can be created, stored for future
reference and analyzed. The FRA application uses
the output of the Arbitrary Wave Generator
(AWG) to generate the frequency-swept signal.
Functions
Bode plots.
Stores plots for future use and analysis.
Precise analysis of the measured data in a plot
with the aid of cursor measurement.
Amplitude profile implemented along with
independent interpolation control for all test
frequency bands.
